Presentknowledge about grape development is mainly driven by the premise that a typical berry would follow the same kinetics as the population average
After the onset of grape berry ripening, phloem unloading follows an apoplasmic route into the mesocarp tissue. In the apoplast, most of the unloaded sucrose is cleaved by cell wall invertases
Grape quality is a complex trait that mainly refers to berry chemical composition, including sugars, organic acids, phenolics, aroma and aroma precursor compounds.
In the last years the application of genomic tools to the analysis of gene expression during grape berry development generated a huge amount of transcriptomic data
